1. When addProtectedField used with custom setters, we need to return false, or it will set the value via regular routine after the method exists (change ParticleData::protectedSetTimes() to return false instead of true).
2. The ParticleData::sizes[] needs a custom setter, so the value is clamped in a range of 0.f and MaxParticleSize.
3. The spinRadnomMin and spinRandomMax ParticleData fields need a FRangeValidator, so it auto-clamped in a range of -1000 to 1000, as we are writing data trying to fit the values in 11 bits (as UInt upto 2048 max).
* The description for those fields needs to be updated to use 1000 instead of 10000.
* ParticleData::onAdd() should check for values to be in a correct range too.
